Issue Description

Can the MTU of the GRE Tunnel Interface Take Effect?

Solution

If you set an MTU value on a GRE tunnel interface, forwarding of data packets through the GRE tunnel will be affected. If the packet length exceeds the MTU value on the tunnel interface, the device fragments the packet.
